1.1 Check the following before taking a sauna bath
1. The sauna room is in an appropriate condition for taking a sauna bath.
2. The sauna room door and the window are closed.
3. The sauna heater is topped with stones that comply with the manufacturer's recommendations; the stones
cover the heating elements; the stones are piled in the sauna heater leaving copious amounts of space in
between.
4. Temperatures approaching 70°C assure a pleasant, smooth sauna bath experience.
1.2 General information on the control panel
Control centre 1601 – 28 (T2) and contactor case 2005 – 14 (WE – 14) can be used with the following sauna
heaters:
- SKLE - .… 1105 - ….
- SKLA - …. 1112 - ….
The Contactor case should be installed outside the sauna room. The cables should be installed using the
protocols for permanent installation. A split box with a semi-permanent installation into the sauna heater should
be attached inside the sauna room. Caution: not adhering to the minimum distances indicated in the Installation
manual may cause a fire hazard.
To ensure that that it is in an appropriate condition for bathing, always check the sauna room before switching
on the sauna heater.

4.2 Control panel functions:
General
‐The control panel is intended for installation outside the sauna room.
‐Maximum bathing time in monitored facility use is 18 hours. With timer control the maximum time is 12 hours,
after which there is a compulsory 6 hour break. The control panel gives an error message if 12 hours is
exceeded. The pause period can be reset from the control panel separately, for instructions see Settings –
Service – Settings – Reset pause timer. In private use the maximum on time for the sauna heater is 6 hours.
‐The available pre-set period for the 24h timer is 24 hours.
‐The control panel includes also a calendar function that can be used to turn the sauna heater ON on certain days
and at certain times. However, this function should not be utilized in monitored institutional use conditions.
‐There is a motion sensor in the front of the control panel. If the control panel senses no movement, it switches
to the screen saver mode to save energy. The activated functions will stay on.
‐The control panel is equipped with a key lock to prevent the misuse of the panel.
‐In accordance with the applicable regulations on electrical devices, only a qualified professional is allowed to
connect the sauna heater and the control panel to the power mains.
‐In accordance with the regulations concerning the sauna heaters, a door switch must be installed for use in
unsupervised conditions to prevent the remote switching on of the sauna heater (the calendar timer or the 24h
timer) while the sauna room door is open.
First time starting up / Restoring the factory settings:
Select the geographic region where the sauna heater is used. After this,
select the appropriate language from the menu using the arrow keys and press OK.
Next, set the time and the date. After each number selection, press OK.
Next, select the intended use of the sauna heater. Your choices are:
‐Supervised facility. Supervised conditions in a facility, such as an indoor
swimming pool,spa or health resort. The maximum
ON-time for the sauna heater is 18 hours.
The timers (calendar, 24h) are not available for turning on the sauna heater
‐Time controlled. Pre-set time to turn on the sauna heater. The maximum
ON-time for the sauna heater is 12 hours. The timers (calendar, 24h) are
available for turning on the sauna heater.
‐Private sauna use. Maximum on time for the sauna heater is 6 hours.
Using pre-set timer is possible. Using calendar timer is not possible.
Next, choose the length of the sauna bathing time. The selected ON-period for the sauna heater may be maximum
allowed or less, in other words, 0–18 hours, 0–12 hours or 0–6 hours, depending on the type of use
Next, choose the use of the door switch. According to the electric device regulations, a Door switch must be
installed and switched ON in circumstances where the sauna heater can be turned on remotely and/or on a
timer, and where no pre-checking of the sauna is performed. Before the remote use, as indicated above, is
possible, the door of the sauna room must be closed and the appropriate option checked in the control panel
as needed. This will make it possible to turn on the sauna heater.

The door switch can be utilized also in supervised institutional and in private use.
Basic mode:
In its basic mode, the control panel's screen is off. As the control panel senses an
object e.g. a hand) less than 50mm from its front surface, the screen activates
automatically. Removal of the object causes the screen to revert to its energy
saving mode, after a designated period. The period to the screen turn-off can be
adjusted to a value between 10 seconds and 5 minutes (see selection: Settings –
General – Period to turn-off).
Turning on the sauna heater:
The sauna heater can be turned on by choosing the START/STOP icon on the front
page (default) and pressing OK. This will cause the sauna heater to raise the
temperature to the one indicated in the control panel memory. Also, the heating will
last the period indicated in the control panel memory. Changing the target
temperature – see below. The sauna heater stays on for the period indicated in
Settings – Maintenance – Settings – Bathing time limit. The sauna heater can be
turned off any time by pressing OK while on the front page.
Pressing "RETURN" while on the front page will bring up the date and time as well
as the sauna room temperature.
Setting the sauna room temperature:
To set the desired sauna room temperature, choose the front page icon that is the
second from the top and press OK. The temperature on the screen is changed by
pressing the up or down arrows. Accept the temperature chosen by pressing OK.
You can set a limit to the allowed temperatures of the sauna room by going to

ON/OFF Push Button (Optional)
The sauna heater can be turned on remotely using the ON/OFF push button, for instance from the hotel reception in
case of requests for non-scheduled sauna use periods. The LED indicator light on the push button will light up to
indicate that the sauna heater has been turned on. As long as the maximum time and temperature have been pre-set
on the T2 Control panel, the sauna heater will stay on. If the calendar timer or the 24h timer has been programmed,
the LED indicator light on the push button will blink slowly. A fast blinking indicator light signifies that the sauna heater
is on Standby (lowered sauna room temperature). If an irregular (non-scheduled) sauna use period is required, the
change in the regular program can be effected from the Calendar, the 24 hour timer or the Standby modes.
